I 3 Claims. 1

This invention relates to an electric heater.

It is particularly aimed to provide a novel construction whereby maximum heat will be attained without the use of a driven or motor-powered fan or other mechanical means of forced c r ulation, to the end that all current consumed will be converted into heat. It will accordingly be unnecessary to provide moving parts and there will be a minimum consumption of electric energy.

Further, an object is to attain the end specified by the employment of elements to rapidly radiate heat transferred to them and by inducing circulation through the principle of rising air.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings- Figure 1 is a front elevation of the heater;

Figure 2 is a vertical sectional view on an enlarged scale taken on the line 2-2 of Figure 1;

Figure 3 is a central vertical sectional view taken through the heater on a line at the right angle to Figure 2;

Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure 1;

Figure 5 is a horizontal sectional view taken on the line 5-5 of Figure 1;

Figure 6 is an electric diagram; and

Figure '7 is a detail section showing one of the terminals of the heating element.

Referring specifically t the drawings wherein like reference characters designate like or similar parts, the structure has an elevated casing gen erally designated I0. This casing may consist of upright end walls or panels II having relatively narrow flanges I2 across the front, and at the rear the end walls II are connected by a wall or panel I3. The wall I3 may be separate from the end wall II or detachably bolted or otherwise connected thereto, as preferred.

Fastened longitudinally across the top of the casing Ill as by means of bolts I4 is a bar while the bottom of such casing has a floor or support I6 detachably bolted as at I! to the Walls II and I3.

A suitable heating element I8 is disposed within the casing I0, approximately midway thereof.

' This element may be of any suitable construction,

for instance, the usual metallic resistance wiring. One terminal of the latter is fastened to a terminal element I9 which is secured in the bottom.

IS in any suitable manner and insulated therefrom at 20, the electric current being applied thereto from any suitable source through a conductor 2| positioned through the aid of acIamp 22 bolted as at 23 to the wall I3 or otherwise. The other terminal of the heater element I8 is connected to a terminal element 24 fastened in the bottom wall I6 and insulated therefrom as at 25, one side of the circuit being connected to the terminal element 24. It will be noted that the heating element I8 passes alternately through guide insulators of sleeve type at 26 and 21, the same detachably mounted as by means of brackets 28 and 29, respectively fastened to the supporting bar I5 and the bottom plate I6.

Across the open front of the casing, a grill is provided in the form of a series of bowed bars 30, preferably detachably bolted as at 3I, in vertically spaced relation, to the flanges I 2.

Bolted in place across the front of the casing Ill below the floor I6, i a panel 32 and mounted by such panel is a control switch 33 which is operatively connected in the electric circuit 2I as best shown in Figure 6.

It will be noted that the casing is elevated from the floor or other support and is mounted preferably by a pair of supports 34 which are open or U-shaped in cross section, such support being detachably bolted as at 35, to the flanges I2 and wall I3, and such bolts also passing through the panel 32 in order to detachably mount the same across the top of the casing.

The top of the casing preferably consists of a series of inverted U-shape or hood elements or sections 36 and 3'1, detachably bolted as at 38 to the wall I3 at flanges I2. It will be noted that the hood section 31 is central, higher than those at 36 and partly extends across the same, but in spaced relation thereto.

The invention provides for radiation of heat by employing a heating element near surfaces which rapidly radiate heat transferred to them, and as the air rises upwardly, its heat is employed to induce circulation. The casing is so arranged that the coolest air near the floor or support will surround the heating element at the bottom plate It. As the air heats, it rises upward inside the casing and such air is continually heated as it rises upward, over the heating element, until it reaches the top. At this point of maximum temperature, the air is ready for its outlet through the hood sections 36 and 31, each of which provides a vent in each side and top through which the heated air passes due to its tendency to rise and be replaced by cooler air. The top or hood 3 sections 36 and 31 also provide additional radiat ing surfaces.

It will be realized that the structure is economical to manufacture, avoids intricate parts, and may be constructed of light gauge metal throughout.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. A heater of the class described having a casing open at the front, supporting means for the casing elevating the same, a heating element within the casing, and a top for the casing comprising generally U-shaped hood sections, one of such sections extending above the remainder.

2. A heater of the class described having a casing open at the front, supporting means for the casing elevating the same, a heating element within the casing, a top for the casing comprising generally U-shaped hood sections, one of such sections extending above the remainder, said means elevating the casing comprising generally U-shaped members open at the top.

3. A heater of the class described having 3. casme open at the front, a bar across the top of the casing. a bottom for said casing, insulators connected to the bar and bottom, heating elements mounted by said insulators, supporting means open at the top connected to the said casing and elevating the latter, an open top for the casing consisting of inverted U-shaped hood sections, one of said sections extending above the other, flanges at the front of the casing, and grill bars extending across said front and secured to the 10 flanges.
